In a recent collab I was included as a contributor along with 15 other amazing people. A friend named Richie who also contributed sent me a file to close caption the video. I had never done that before and he was kind enough to tell me how to do it.
On December 28th I added close caption to several of my videos. I will try to add them from here on. I am not a good typist so it's difficult for me to do. But, having a hearing loss myself, I feel strongly that everyone should enjoy YouTube videos. The program is named Media Subtitler and it is very easy to use.
